The Germany international, 24, has long been linked with a move to the Spanish champion, and a number of recent reports suggested that BVB is ready to let go of Hummels if a 35 million euro offer comes in.

Watzke, however, has laughed off the rumors

"That is absolute nonsense," Watzke told ZDF. "This is a complete non-story. There's no truth whatsoever in these rumors."

Hummels, who has made 12 appearances this season for Jurgen Klopp's side, has a contract with Dortmund until June 2017.
